  1. Exploratory factor analysis based on principal component analysis and with Kaiser criterion (eigenvalue > 1).
  2. *Factor loading represents the correlation between items and factors.
  3. #Communality represents the proportion of variance of each item that can be explained by the factor.
  4. The factor structure was determined considering items with factor loading and communality greater than 0.5.
